Purportedly the cats of the city know a secret or two. The common tabbies and gingers can convey little more than gossip, the whites are deaf but keen-eyed, the greys and blacks know some real treasures.

Sweeping up crowds of yowling alley mogs in a net is technically possible, but not the mark of a true knight of the streets.
